I need to calculate the following integral Integrate [(Sin[x])^2 rho Exp[I n x],{x,0,2 Pi}] as a function of the two parameters rho and n. I have tried it for rho = 1, 4, 8, 10, and it works, but it doesn't work at all for rho = 12. I left the computer on all night but only got the same expression as a result. Any suggestions?
